sometimes I get the very strange sensation of the T/C or upper T spine feeling like it is pulling apart.

like reaching out over the couch to pull or push the large slider window open or closed. gotta get some silicone for this year so it will slide easy.

the leaning over to pull weeds of pick heavy objects from floor can at times cause this too.

One of my Dx's was cervico-thoracic spine strain with arm pain- this was from a physiatrist - his adv PT guy that actually did the full evaluation - {dr did not do it}- PT did find TOS sx - but dr did not change his Dx after the eval.

I think I do have both after doing kitchen remodeling project last summer, the spine strain seemed to appear again- lots of lifting, bending, carrying.
